Hi,

Is this some early April fool joke? =P Not sure where you got those strange dates from. Just before you confuse yourself, and the others, any further :roll:, I think you have some major misconceptions on what solstices and equinoxes are. Basically, it's to do with the positioning and angle of the sun either above or below the celestial equator, and has nothing to do with specifically how many constellations you are able to see in a single night. As for the two different months which you mentioned somewhere, March and September, the events that occur are the Vernal and Autumnal Equinox respectively. To enlighten you, the 22nd-23rd September event is an Autumnal Equinox instead of a Winter Solstice.

FYI,
Vernal Equinox.......(SPRING) MAR 20 - 21

Summer Solstice....(SUMMER) JUN 20 - 21

Autumnal Equinox...(FALL) SEP 22 - 23

Winter Solstice.......(WINTER) DEC 21 - 22

Yeap, you are right about the winter solstice having the shortest daytime. The specific date and time of this event next year is on December 22, 2006 at 00:20 UT. However, note that the indicated time is only a prediction, so you can expect some slight variations on the actual day itself. For more info on this, you can refer to the following link:

http://scienceworld.wolfram.com/astrono ... stice.html


If you wish to plan any activities on the 3 other events and need their dates as well, you can use the same website to browse through.

As to whether you can see nearly all 88 constellations in a single night, I think there's a reason why those scientists even bother to classify all the constellations under Spring, Summer, Autumn and Winter constellations. *Hints hints* :wink:

Hope this helps to clear up some of the confusion, and all the best in your plans on the upcoming events.. :)


Cheers,
:cheers:

He is actually refering to seeing all the Messier Objects in a night, not all the constellations.

Have a nice day.
